WILLIAM B. FENN,

0F YORK, N. Y., ASSIGN'OR TO MARGARET F. FENN, OF

NEW YORK, 1s. Y.

To all whom it may concern:

Be it known that I, WILLIA B, FENN, a citizen of the United States, residing at New York, in the county and State of New York, have made a certain new and useful Invention in Means for and Methods of Removing the Cores from- Fruits, of which the :following is a specification.

This invention relates to'means for and method ofremoving the cores from fruits. The object of the invention is to provide a method of removing the cores which is simple and efiicient for the purposes re uired. .f v

further object of the invention is to provide a device which is simple in' character, but eflicient in operation, in connection with the method employed in accordance with my invention for the purpose hereinafter set forth.

A further objectof my invention .is to provide a device of the character'set forth which may be used in connection with means and the method of removing the core from fruits.

-Further objects of the invention will appear more fully hereinafter.

- The invention consists substantially in themethod employed and in the construction, combination, location and relative arrangement of parts, all inafter set'forth,

use required thereof, moved, such, for instance, as .for canning, or similar processes, which requires the cores of the fruit to be removed prior to the usual processes to which the fruit is ordinarily subjected.

While I have shown and will describe in connection with Fig. 1 of the drawing, the present invention, as applied in connection with means for removing the skin from the fruit, as being one of the steps taken in the process of preparing the same for canning, I wish it to be understood that my invention is not to be limited in'this same may be readily applied in any connection regardless of the use to which the whether for canning, or for use immediately after the core has been removed. Further, will presently describe my invention as applied to a tomato, I wish it to be understood that the use of the tomato is merely for illustrative purposes and my invention can be used in connection with any fruit containing a core.

In accordance with my invention, I imtomato upon a .hollow circular member, which member is of suflicient height and width to completely inclosc therein the core of the tomato.. The member referred to is provided with a sleeve member through which fluid pressure of desired strength or material is passed. This fluid pressure passes inwardly from the sleeve and in effect cuts the core of the tomato from the est of the tomato body and the core is thereupon removed 1 any desired manner.

Referring to F ig. 1, I show an inclosedchamber which is diagrammatic of the with the cores re-' while I have shown andrespect as the means employed for removing the 'skin from the tomato, as shown and described in detail in my Letters'Patent No. 1,243,724, issued to meOctober 23, 1917.

As the details of construction thereof form no part of the present invention, I will merely describe the same generally as a casing 1, which forms a chamber 2 therein, in which chamber the fruit, which in this intomato 3, is sup- .ported in the chamber by the corer indicated'generally at 4. The corer consists of a portion 5 provided with screw threads 6 at the end thereof to screw into casing 1 as shown in Fig. 1. The portion 5 is preferably circular-and is provided with a circular central opening extending through the longitudinal length thereof, within the other end of which is inserted a sleeve 5 member 6, which is likewise provided with a central opening therethrough, the two central openings of the members 5 and 6 being in alinement with each other as shown in Fig. 2. The end of the member 6 is provided with teeth 7 which are preferably sharpened to allow theto mate to be more readily impinged thereon. The central opening of the member 5 at its npper'end is of larger diameter than at its lower end, and wall 8 thereof is secured to the member-(i in any suitable way, for example by welding, brazing soldering or the like. In efl'ect, this forms a circumferentially extended passage 9 around the upper end of the member 6, which passage is in communication with the source of fluid pressure through port 10, extending through theside wall of the member 5. The fluid pressure enters through the port 10, circulates around passage 9 and passes horizontally, through the member 6, through ports 11, of any desired number spaced circumferentially around the member 6 as shown.

The fluid pressure employed may be'of any desired nature or strength as hereinbefore stated, suitable for the purpose, that is, which is not injurious to the fruit'being cored. As set forth in my co-pending application above identified, I find steam to be one example of eflicient character of fluid pressure for this purpose. 'hen the present dc vice for coring the tomato'is used in connection With the chamber in which the tomato is inclosed while being subjected to the process of removing the skin therefrom, it will be seen that the core 12 of the tomato is completely inclosed within the central opening of the member 6, which opening, communieating through the central opening of the member 5, is in communication with the exhaust port 13 of the casing 1. The fluid pressure, in this instance steam, is admitted to\ the chamber 2 in any suitable way, as described in my co-pending' application above identified and into port 10 of the member 5, so that the steam passes through the passage '9 and jets horizontally across "the portion of the tomato inclosed by the member 6, through ports 11. This cuts off the core 12 so that when the passagejl 3 is opened to exhaust the core of the tomato which has thus been severed from the body the tomato is forced out by the steam pressure through v this passage.

It is obvious that different size corers may be employed for different size fruit or for different size cores of the various fruits, so, as i'sreadily apparent, anvsuitable means may be employed for -controlling the dis- 5 tance into. the fruit the member 6 extends.

By this I mean in some fruits, such as apples,vthe core extends substantially through the entire apple in which case the corer would extend substantially the same dis tance, whereas in tomatoes, as shown, the core only extends a short distance into the body of the tomato, in which case the corer likewise extends but a short distance. This adjustment of the corer may be readily secured, where different size corers are not utilized, by placing washers or the like on the seat 15, formed on the member. 5, in any desired sizes or numbers, which washers will limit the degree of penetration of the corer into the fruit, and will at the same time atford a seat for the fruit or vegetable thereon.

Many modifications of my invdntion will readily occur to those skilled in the art,

without departing from the snirit or scope of my invention as defined in the claims. For example, in Figs. 3 and 4, I show a modified construction of corer, wherein the same is made in one piece. In this instance, the member 5, at its upper end has a comparatively thicker wall than the lower portion thereof and a plurality of vertical extending passages 16 are bored therethrough as shown for the passage of the fluid pressure.

If desired the seat 15 may be provided with pins 17 to prevent the fruit from turning on the seat or from blowing off when subjected to the fluid-pressure, as will be readily understood.

aving now set forththe objects and nature of my invention and having shown and described specific structures embodying the device thereof, what I claim as new and useful and of my own invention and desire to secure by Letters Patent is:
